Iyo Firimu Yekugadzira Maitiro eRDP muCement Mortar
Iyo firimu yekugadzira maitiro eRedispersible Polymer Powder (RDP) mumatope esimende anosanganisira akati wandei matanho anobatsira mukugadzirwa kweyakabatana uye inogara kwenguva refu yepolymer firimu. Heino mhedziso yemaitiro ekugadzira firimu:
- Kupararira: Pakutanga, zvidimbu zveRDP zvinoparadzirwa zvakafanana muchikamu chemvura chemusanganiswa wesamende. Kupararira uku kunoitika panguva yekusanganisa nhanho, uko RDP zvimedu zvinounzwa mumusanganiswa wedhaka pamwe chete nezvimwe zvakaoma zvinosanganiswa.
- Hydration: Pakusangana nemvura, iyo hydrophobic polymer particles muRDP inotanga kuzvimba uye kutora hunyoro. Maitiro aya, anozivikanwa se hydration, anoita kuti mapolymer particles apfave uye awedzere kuchinjika.
- Kugadzira Firimu: Sezvo musanganiswa wedhaka uchiiswa uye uchitanga kurapa, iwo hydrated RDP zvimedu zvinobatana uye kuungana pamwechete kugadzira inoenderera yepolymer firimu. Iyi firimu inonamatira pamusoro pematrix edhaka uye inosunga zvidimbu zvega pamwe chete.
- Coalescence: Munguva yekurapa, ari padyo neRDP zvimedu zvinosangana uye zvinosangana, kwazvinobatana uye kugadzira intermolecular zvisungo. Iyi coalescence process inobatsira pakuumbwa kwekubatana uye kuenderera mberi kwepolymer network mukati mematope matrix.
- Crosslinking: Sezvo dhaka resimende richirapa nekuomesa, kemikari kuyambuka kunogona kuitika pakati pemacheni epolymer mufirimu reRDP. Iyi nzira yekubatanidza inowedzera kusimbisa iyo firimu uye inosimudzira kunamatira kwayo kune substrate uye zvimwe zvikamu zvedhaka.
- Kuomesa uye Kubatanidza: Iyo simende inoomeswa uye kubatanidzwa sezvo mvura inoputika kubva mumusanganiswa uye simende inosungirirwa inopora. Maitiro aya anobatsira kusimbisa iyo RDP firimu uye kuibatanidza mune yakaomeswa dhaka matrix.
- Yekupedzisira Firimu Kuumbwa: Pakupera kweiyo nzira yekurapa, iyo RDP firimu inokura zvizere uye inova chikamu chakakosha chesimende yedhaka chimiro. Iyo firimu inopa kuwedzera kubatana, kuchinjika, uye kusimba kune dhaka, inovandudza kuita kwayo kwese uye kuramba kuputika, deformation, uye kumwe kushushikana kwemagetsi.
iyo firimu yekugadzira maitiro eRDP mune simende dhaka inosanganisira hydration, coalescence, crosslinking, uye consolidation nhanho, iyo pamwe chete inobatsira mukugadzirwa kweyakabatana uye yakasimba yepolymer firimu mukati mematope matrix. Iyi firimu inosimudzira kunamira, kuchinjika, uye kusimba kwedhaka, inovandudza mashandiro ayo mumhando dzakasiyana dzekuvaka.
